Its neat that phajdan.jr is working on fixing chromium to make the pulse dependency optional: https://codereview.chromium.org/12963004/ https://groups.google.com/a/chromium.org/forum/?fromgroups=#!topic/chromium-dev/hvPEhBGhIUg https://code.google.com/p/chromium/issues/detail?id=222355
(In reply to comment #0) > [ebuild N ] dev-libs/json-c-0.9-r1 USE="-static-libs" > [ebuild U #] www-client/chromium-27.0.1444.3 [27.0.1438.7] > [blocks B ] dev-libs/jsoncpp ("dev-libs/jsoncpp" is blocking > dev-libs/json-c-0.9-r1) You're mixing stable with unstable here - just unmask more recent jsoncpp or json-c. I think this will be resolved naturally as we move new jsoncpp to stable, but I'll keep the bug open just to remember about it and maybe test some more.
pulseaudio-2.1 and chromium-26.0.1410.43 are stable and cannot be installed together because of this issue
+ 04 Apr 2013; Mike Gilbert <floppym@gentoo.org> json-c-0.9-r1.ebuild: + Update blocker; newer jsoncpp does not collide. Bug 462434.
